Signing in to Netflix activates my deactivated Facebook account :-(

How do,
I deactivated my facebook a few months ago for procrastination reasons. A lot of my work is computer based and don't need the distractions at the moment. I will reactivate at some point from now because I have a lot of friends from the past that it's my only link to, also a lot of history about me so anyone who reccommends to delete it permanently, keep your advice to yourself please .

Anyway, have a Netflix on my PS3, pretty much all I use the PS3 for at the moment but every now and again, it asks me to log in again. I usually don't have to, just logs me straight in but sometimes it comes up with my username and password already entered and all I have to do is click okay. When I then check my email, I get a 'Welcome Back to Facebook' email from facebook. Seems whenever I have to log in, it takes it as logging into facebook which is all it takes to reactivate your account.

This has happened twice now in two months and it's really annoying me. I've gone into my facebook apps each time it's logged me in and deleted all apps netflix related or otherwise, but sure enough after a while I'll have to log in again on my PS3, which in turn activates my facebook, I have to go back on, delete all the apps that have magically reappeared and deactivate it again :mad:.

Sometimes, if I see that it wants me to enter my details again, I'll turn it off and come back in an hour and I'll be automatically logged in without me having to confirm, thus no facebook. Anyone have this happen before? What can I do to permanently severe my ties with facebook from Netflix. It's very annoying.
